To all whom t may concern:

Be it known that I, CHAnLEs J. `DUN- BAR, a citizen of the UnitedStates, residing at Kalamazoo, in the county of Kalamazoo and State ofMichigan, have invented certain new and useful Improvements in Loose-Leaf Binders and Posters, of'whicli the Ifollowing is a specification.

invention relates to improvements in loose leaf binders'and posters, andmore particularly to that type in which typewrittenfl record sheets arearranged and temporarily bound in such a manner as to permit of theready removal or insertion of sheets without undue wear on the latterand without disturbing the arrangement of the remaining sheets.

flhe primary object is to provide a generally improved loose leaf binderand posting apparatus which will be etceedinglyl simple in construction,cheap of manufacture, and

efficient in use.

A further object is the provision of a loose leaf binder of the posttype in which one or more leaves may be readily removed without theremoval of the binderpposts when the binder is adjusted to loosen theleaves or segregatethe same into blocks on the posting stand or rack.

A still further and important object is the provision of an improvedsupport or stand provided at one end with aiXed guide or abutmentadapted to support a ledger base or bottom cover and its leaves ineither a vertical or leaf-segregating and blocking position, or in aninclined horizontal or posting position-together with an improvedfollower guided on said support or stand and to cooperate With saidfixed guide or abutment in supporting said ledger base'cover and leavesin either of said positions and in forming a posting tray in thefirst-mentioned position.

A still further object is the provision of an improved binder and bindersupport or stand having their parts so arranged and disposed relative toeach other as to permit of the utilization of the covers of the binderas tray elements in receiving and aligning the leaves upon which entriesare made, permitting ready transfer and rearrangement of such leaves bydetachment and replacement thereof.

ting posts, together with loose leaves having an improved form andarrangement of notches and perforations with constricted slots at thebutt edges adapted to engage the posts so that all the leaves may bearranged in alignment or certain of the leaves may beplaced in offsetrelation with reference to such aligning or registering leaves andall'the leaves locked in the binder in either arrangement.

Vith the above mentioned and other ends in View, the invention consistsin the novel construction, arrangement and combination of parts,hereinafter described, illustrated in one of its embodiments in theaccompanying drawings, and particularly pointed out in the appendedclaims.v

Referring to .the drawings, forming a part of'this specification, Figure1 is a perspective View of the improved loose leaf binder support orstand, the relatively movable mem rl or follower block being movedtoward and in-cooperative relation to the fixed member for engaging andholding the connected ledger covers in a vertical or tray-formingposition.

Fig. 2, an enlarged fragmentary end elevation of the same with the looseleaf ledger supported therein for segregating the leaves into blocks or'sections, and for offsetting, and the like, certain portions beingbroken away for clearer illustration of the connected parts.

Fig. 3, an enlarged side elevation of the improved support or stand, thefollower block being in its fully extended or Verticallyoffset fixedposit-ion for supporting the lower or pin-carrying binder member and theattached ledger base cover in a posting position.

^ Fig. 4, an enlarged detailed side elevation of one of the improveddetachable leafregistering or off-setting posts, and the postreceivingsocket in disassembled -position preparatory to the insertion or justafter the removal of the improved post.

Fig. 5, a top plan view of the post-receiving or socket member shown inFig. 4.

Fig. 6, a. top plan View of a slightly modified form of post-receivingsocket members, detached.

Fig. 7, a cross sectional view of the Asame taken on line 7,-7 ofFig. 6.

Fig. 8, a fragmentary top plan view of one of the loose leaves or sheetsprovided with an improved form'and arrangement of post-receivingrecesses and of eyes or openings having constricted slots adapted tocooperate with the leaf-registering and olfsetting posts. .l

Fig. 9, an end view of the lower binder member, the binder posts beingshown mounted in their normally spaced relation.

Similar numerals of reference designate like parts throughout all thefigures of the drawings.

The clamping or binder members l and 2 may be of any suitable andconvenient construction and so likewise the hinged upper and lower covermembers la and 2 a respectively. The upper or follower binder member lis provided with post-receiving openings lb, to removably receive andcontain the binder posts, hereinafter referred to. The upper binder 1and its cover la are movable relatively to the lower or base member 2and its cover 2a, the post-receiving and containing openings 1b beingslidabl on the posts and being secured in any desired adjusted positionby suitable post-engaging and clamping mechanism, but such mechanismforming no specific .part ofthe present invention, the same need not beshown or described in detail.

As a means of mounting and demounting the binder posts 3, in the base orbottom binder member 2, the latter is preferably provided on itsinterior with postsreceiving socket members or blocks 4, provided withpost-receiving sockets or openings 4, to removably receive and containthe lower ends of the binding posts 3.

As a means of conveniently inserting and locking or of unlocking andremoving the. binder posts 3, the latter are preferably provided attheir lower ends with spirally arranged grooves 3, preferably of squareshape in cross section, said spiral grooves or threads 3l being adaptedto receive and engage with a square shaped rojection 4b in the socketopening 4a. If esired, however, the projection pin 4b may be replaced byspirally arranged screw threads 4, to receive the grooves 3a of the pins3, as illustrated in Figs. 6 and 7 of the drawings.

Referring now to the improved loose leaf or sheet 5, having intermediateslots orrecesses 5a, and post-receiving eyes or openings 5b, providedwith constricted slots 5, as shown most clearly in Fig. 8 of thedrawings, it will be understood that the intermediate recesses 5*1 andthe eyes and slots 5b and 5c are adapted to receive and cooperate withthe intermediate and end posts 3,-re spectively, in the leaf-registeringand offsetting operation. The inner ends of the recesses 5a and the eyesor openings 5b are approximately of the diameter of the posts 3 and itwill be seen that the constricted slots 5c are formed or defined by theoppositely arranged rounded tabs 54,'and it will yor fixed member 7 tabs5f is such that when not compressed or restrained by adjacent sheetsorleaves such "tabs will be able to pass about the binder posts 3 in theinsertion or removal of a single sheet when thev binder posts are inposition and the sheets are loosened or segregated into blocks, as shownfor example in Fig. 2 of the drawings.

When used as an ordinary ledger and it is desired to retain the sheets 5in position as against longitudinal movement or detachment relatively ofthe binding posts 3, three of such posts are used as shown. When it isdesired to offset certain .of the leaves or sheets, the two end posts4are preferably ref' be obvious that the natural flexibility ofthe imoved, leaving the median or middle post tov l stand and utilizing thesame' as an offsetting post in connection with the three intermediateslots or recesses 5a, and should it be desired to lock the registeringleaves in position in connection with the offset leaves, one or more ofthe end posts may be inserted.

Referring now to the improved support or stand for a loose leaf ledgeradapted to support the covers of the latter in a vertical position astray members, as shown in Fig'. 2 of the drawings, or to carry thepin-carrying or lower binder member 2, and the lower or base covermember 2a in a posting position, as shown in Fig. 3 of the drawings, itwill be seen that a base or support 6, is provided having relatively xedand movable members 7 and 8, respectively, adapted when in one positionto support the ledger covers l*1 and 2a, respectively,-in a tray-formingposition and in another position to support the base or bottom cover 2ain a horizontally inclined or posting position. The abutment 'referablyextends upwardly and outwardf) as shown, at one end of the support orbase 6, and the relatively movable member 8 is preferably in the formlof a follower block slidvablvand adjustably mounted on the base 6 andmovable toward and from the fixed or abutment member 7. As a convenientmeans of guiding and adjusting the follower 8, the latterl is prefer!ably provided on its under side with guide and stop members, said guidemembers, in the present instance, consisting in forwardly extendingguides or blocks 8a arranged, in the present instance, in longitudinallyextending guide-ways or slo-tsa. As a means of securing the follower 8in variable positions, the stop members, in the present instance,comprise de ending stop pins or projections 8", adapte to extend intosuitably spaced stop pin receiving openings 6b, ar- 125 follower blockinto cooperative relation to the ledger irrespective of variations inthe lengths of the posts 3 and of variations in the thickness oftheloose` leaf ledger, the follower block is preferably provided withpost-receiving openings 8c, to receive the tops of the posts 3, as shownmost clearly in Fig. 2 of the drawings. l p

As a means of conveniently carrying and supporting the lower bindermemberv 2 and the base cover 2 in proper relative position to theabutment 7 and the follower 8 when the latter is in its extended orelevatedposition for supporting the leaves in a posting position, asshown 1n Fig. 3 of the drawin s, the guide blocks 8*aL are preferably infiile specific form of offset ledges having notches 8f1 on their upperportions and the rear end of the base or support 6 is provided with avertically offset or elevated member 9, provided at its opposite endswith openings 9", to receive the stop pins 8b of the follower when thelatter is set up in its extended or posting position.

' Having thus described one of the embodiments of my invention, withouthaving attempted to set forth all the forms in which it may be made, orall the. modes of its u'se, what I claim and desire to secure by LettersPatent is,-

1. A loose leaf for temporary binders pro'-- vided with-post-receivingeyes having con- V stricted slots and a plurality ot'y intermediateequally spaced leaf-offsetting recesses intersecting the butt endsthereof.
